Abstract
Acoustic fields of consumable electrode shielded-gas welding processes with a fine- and coarse-drop metal transfer were investigated experimentally. The prospects of application of acoustic field of the welding process for control and monitoring of its quality are discussed.
Keywords: arc welding, consumable electrode, acoustic field, electric characteristics, high-frequency oscillations, arc pressure, defects of join
